Ubuntu is able to be used as a hypervisor, as an alternative to PowerKVM. Just install in bare metal (NV) it following the steps in Running Ubuntu non-virtualized on POWER8
After the installation you need:
 1. Install the missing virtualization packages:
 {{{# sudo apt-get install qemu-user qemu-utils cloud-image-utils qemu-system-ppc qemu-slof libvirt-bin numactl}}}

 1. Add the users that would be able to run virtual machines into the kvm group:
 {{{# sudo usermod -a -G kvm <user>}}}

 1. Disable the SMT:
 {{{# sudo ppc64_cpu --smt=off}}}

 1. Enable KVM module in the kernel (Add a line "kvm_hv" in /etc/modules in order to automatically load it after a reboot):
 {{{# sudo modprobe kvm_hv}}}

 1. If you hit "failed to parse default acl file `/etc/qemu/bridge.conf", you need to edit (or create) file /etc/qemu/bridge.conf and add:
 {{{allow br0}}}
 1. If you hit "failed to create tun device: Operation not permitted", you need to set the setuid attribute:
 {{{# chmod u+s /usr/lib/qemu/qemu-bridge-helper}}}
